We learned all the prefixes between milli and kilo (milli, centi, deci, deca, hecto, kilo); even the non-metric US has rulers marked in cm, and of course a millilitre and a cubic centimetre are the same. There seems to be less of that today. (I also recall being taught how many quarts in a peck, and how many pecks in a bushel, which my kids aren't learning.)
